Anecdotal: I've heard that in Europe EM emissions directives have exceptions for microwave ovens, because without the exceptions none of them would pass the tests and make it to market.
Never checked if true. But that could explain why they're so "leaky" at 2,4 Ghz (and other frequencies).
- namibj 3y agoThe radiation is in an ISM band, which has no far field emissions limits beyond "be reasonable". The close-range limits are about safety for living being and other devices nearby, so e.g. not cooking you, and not frying your phone's WiFi receiver.
- bonzini 3y agoIn terms of dB they're not that leaky. However when the typical wifi power is on the order of microwatts or tens of nanowatts, it's not hard for an 800 W oven to completely drown that signal and/or overload the front-end.
